Function nalgebra::cast

pub fn cast<T, U: Cast<T>>(t: T) -> U

Converts an object from one type to another.

For primitive types, this is the same as the as keywords. The following properties are preserved by a cast:

• Type-level geometric invariants cannot be broken (eg. a cast from Rotation3 to Rotation3 is not possible)
• A cast to a type with more type-level invariants cannot be done (eg. a cast from Matrix to Rotation3 is not possible)
• For primitive types an unbounded cast is done using the as keyword (this is different from the standard library which makes bound-checking to ensure eg. that a i64 is not out of the range of an i32 when a cast from i64 to i32 is done).
• A cast does not affect the dimension of an algebraic object. Note that this prevents an isometric transform to be cast to a raw matrix. Use to_homogeneous for that special purpose.
